Imac has 2tb internal drive, can i use a 2 tb external for TM?

I wiild like to use a 2 tb drive to backup my imac (2tb) with TM. Does time machine do a full disk backup or only the used memory? I haven't seen and drives larger than 2tb if this wont work.

TM as any other backup tool backs up used disk space, not the whole disk capacity. how much data do you have on the internal drive? note that TM drive should generally be at least two times bigger than the total amount of data you are backing up. you might want to look at a RAID array to use as a backup drive if you don't satisfy that ratio. or you can use a different backup solution which doesn't require as much space on the backup drive. see this post by kappy for options

  • My imac has no iDVD what can i use instead

    I want to burn dvd on my imac and iDVD is not available. What can i use now?

    What exactly do you want to do, if you simply want to burn some data onto a disc then right click the files and click Burn. However if you want something more robust you can buy something like Roxio Toast.

  • I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    In the Mac side of things, backups usually come in two flavors: clones or incrementals.
    A bootable clone is a bit-for-bit copy of all essential files in the startup volume. If using the Lions, clones can be made using CarbonCopyCloner or just plain old Disk Utility. These backups represent the safest protection of your info, but take the longest to do. Recovery is an inverse process: you copy the clone back into the internal drive.
    Incremental backups start with a complete backup of the startup volume and only copy whatever changed from the previous run. OS X includes the fully integrated Time Machine backup utility to do this. It is extremely easy to do and takes the least amount of time. Recovery is another matter altogether since you have to start with a freshly installed instance of the OS and have to apply all intervening backups to bring the result to the latest saved version.
    As for where the backup takes place, the recommended media is an external dedicated drive or drives connected via the fastest interface available on your Mac: Thunderbolt, USB3, Firewire, or USB2. Network-based backups, wired or wireless, are attractive but may not offer the same performance and hence take longer. Also important to note that the entire drive need not be completely dedicated to a single backup. The Mac's EFI firmware infrastructure allows for an unlimited number of partitions on a hard drive and each can be used for either type of backups.
    Holler if you need specifics on how to do each. This was just an executive summary.

    You want system, data, backup etc. Make good use of the four internal drive bays.
    You will have to use Disk Utility to ERASE or click on drive and use PARTITION to make it Mac writeable.

    You may use any 2.5" SATA notebook drive not higher than 12.5 mm that uses either 1.5 or 3.0 Gb/s interface. Visit OWC for available options and prices.

  • I have an 2tb time capsule 802.11n Wi-Fi base station can I use this as an external hard drive and use a new airport extreme  802.11ac Wi-Fi for my wifi?

    You can use the 2 TB Time Capsule as a network drive. That means that it must connect to one of the Ethernet LAN <--> ports on the new AirPort Extreme, or connect to the network using wireless.

  • Two 2TB internal drives in tandem for Time Machine; only one backup deletes.

    I'm using two 2TB internal drives in tandem for Time Machine and deleted some backups while in Time Machine. They deleted from drive A, but drive B still has the files. Is there a way to delete these? I tried unmounting drive A in Disk Utility but then I can't enter Time Machine.
    I love the dual backups, but should I be able to do dual deletes of all backups? I don't see a way to accomplishg this except to force Time Machine to do a backup, then do that again so it switches drives, but that seems a bit convoluted.
    If one of you guru types has an answer I'd be most interested.
    Thanks.

    You can manually deal with this by using the "Browse Other Backup Disks" function which is accessed via holding the opt/alt key and while selecting the TM icon in the menu bar.
    You can then delete the instances of the desired files in each backup set.
    Not elegant, but I wouldn't expect that this will be done automatically, as there are a lot of permutations of how you use multiple backup sets.

  • I have an iMac with 2 internal drives and set-up with multiple user accounts.  How do I create a path to store data files on my second drive within an application?

    I have an iMac with 2 internal drives and a multiple user account set-up.  Hw do I create a path to store data files on the second drive within an application?

    This is the Mac mini forum not the iMac forum however...
    Applications written for average users like Photoshop, Word, i.e. GUI based applications provide a 'Save' dialog box which while allow selecting second drives or any drive. The dialob box initially shown might be in the simple mode but you just need to click on the triangle to show the full set of options. You should then see the different drive names amongst other options.
    If your referring to an application your writing yourself then you need to build a pathname. This can be in one of two styles depending on the programming system your using. This could be a POSIX style path or a Mac style path.
    POSIX = /Volumes/volname/foldername
    Mac style = Volname:foldername:

  • The new iMac has no cd drive so how do I download software that I have?

    The new iMac has no cd drive so how do I download software that I have? I have adobe photoshop elements 11 and baboo drawing pad and they both have CDs to install.

    Welcome to the Apple Support Communities
    The new iMac hasn't got a SuperDrive to insert CDs and DVDs, so you can't install software from CDs and DVDs.
    Instead, you have different ways to install the applications you have on DVDs:
    1. Buy any external optical drive for your Mac and use it to install your applications.
    2. If you have another PC or Mac, you can save the external optical drive cost and use Remote Disc > http://support.apple.com/kb/HT5287?viewlocale=en_US&locale=en_US Note that this may be a bit slow

  • The computer I use for Itunes only has XP so I can't use ICloud. My desktop has Vista so I can use it. But I don't want to lose all of what I have on my Iphone 4S and my two Ipads. How can I use the desktop and retain the apps, music, podcasts etc. I have

    The computer I use for Itunes (my laptop) only has XP so I can't use ICloud:(
    I have a desktop that operates using with Vista.
    I downloaded 10.5 and sought to sync my two iphones and two ipads with the desktop in order to use ICloud. However I got warning messages that if I synced with this computer that had none of my extensive library of apps, music, podcasts, etc. would be on it, I would lose it all.
    I did authorize the computer. I knew enough to do that but am terrified that I will lose everything that I have accumulated and still won't be able to use ICloud.
    Isn't there a way to do this? Shift my library FROM my devices to the desktop?
    Thanks

    This is a tedious solution, which is stupid!  And some users report an inability to reauthorize a computer after an "en masse” deauthorization.  I can’t believe Apple doesn’t provide a list or menu to find out which computers you’ve authorized! Obviously, APPLE knows (or else they couldn’t tell us how many computers we have authorized)--so why can’t they give us access to that information about our own computers??!!!
    And for an already-authorized computer with a hard drive that’s since been replaced and upgraded from Mavericks to Yosemite, would it be recognized as a “new computer” and require authorization? Would its previous incarnation (i.e., with the old hard drive and OS) be considered a separate computer? Some users report they can’t authorize a computer after an OS upgrade because of that. Can’t believe we have to do such a bass-ackwards kludge!

    Paragon even has non-destriuctive conversion utility if you do want to change drive.
    Hard to imagine using 3TB that isn't NTFS. Mac uses GPT for default partition type as well as HFS+

  • Can i use applications from an external hard drive?

    Can i use applications from an external hard drive?

    Photoshop itself needs to reside inside of it's Applications folder so that it has access to it's Libraries and plugins. So if you are going to attempt to store and run it from an external drive you need to copy the whole Application folder or install it directly to the external drive. Even still I am not 100% positive it will work as I know it still needs to access your Library/Application Support for additional files and licensing.
    Why do you want to run Photoshop from an external drive?

    Welcome to Apple Support Communities
    Open System Preferences > Users & Groups > Login Options, press the padlock at the bottom left corner of the System Preferences window and choose the second user account next to "Automatic login". Your computer will always log in to this user account whenever you start up Mac OS X.
    If you haven't got anything in the first user account, you can remove it from System Preferences > Users & Groups after logging into the second user account

    My family has multiple iPhones.  Can we use one Apple ID for all of our phones?

    If you use the same AppleID for iMessage and iCloud though, you will all be sharing the same message account and iCloud email account.  You can use a common AppleID for purchased content, but each create your own unique AppleID for iMessage and iCloud so you each have your own private accounts for those services.
